zen of the UnitedStates,and fresidentoi' ltuthv'en, in the county of Fallov- Alto" and State of iowa', have invented Ya 'certain new and useful Gate-Operating Device, of which thel following` is a specification. y

My invention relates tov that class'v of gate" y operating devices in' which the. gate issup-v 1o ported for `longitudinglj movement to open.

and' close, 'and the gate 'opening 'and closingr device` is lopueratedby pullingl onl a. lever at either*sideoi` the gate to open or'olos'e it.

My object 'is to provide a gate operating device 'of this'classof simple', durablejand inexpensive construction and which maybe operatedto open or close co'nveniei'itlyV and" easily and with a minimum of appliedrv power. p

More specically it ismy object" to proviole improved, means for: supporting the gatev in its sliding, tiltingm'oveinent and to combine with this gate supporting means an automatic latch deviceV arranged to coact arrangement and combination of the various parts of the device, whereby, the objects contemplated are attained as hereinafter more fully set forth, pointed out in my' claims and illustrated in thel accompanying drawings, in which:

. Figure 1 shows a side elevation of a gate with my 'improvedv gate operating device ap'- plied'th'ereto; ln' this iigurethedot'ted lines show the gate in a partly open position 'and also in an open position. Y Figure 2 shows a top or plan view of saine. p

Figure 3 shows an enlarged detail end view taken on line 3-3' of Figure 1.'

Figure/1 shows a detail view ilhlis'trating' the automatic latch device,Y and' ing lever'or releasing the latch upon the Figure 5 5 afdetailsejctional View on the `line 5;;5' "of 1Figure 3l n Referring to the accompanying drawings, l have used the "reference` numeral y10^to i`n`- d'cate the gateproper, whi'chis of ordinary" construction'. ln the present 'instancev the gatel is preferably vmade of a rectangular frame of .pipes having woven wire fixed within ythe pipes. K

*Er'ecfted adjacent t'o one 'endof the gate are two yuprights 11 spaced 'apart 'on opposit'e sides of thev 'gate' and connected at their upper ends the`v brace :12. Y

lin order toA tiltingly and slidingl'y sup-v port vthe gate l have fixed' to onel end of the gate across `bar 13 having slotted'openings in' vits ends, as shown -in Figure, 3. Fflxfedlto the uprights 11H at one end and to stationary post 15 'at the other end are 'two horizontally arranged guide rods 16 extend'- ing 'romth'e upfriglits 111 and in 'a direction opposite from the opening in the fence. By this means 'one end of the gate is slidingly4 supportedl above' the ground.

'At the 'lower ends of the uprights 11 is a cross bar17to which 'l have pivotally connectedfth'e levers 18, r which levers'extend upwardl'yy and outward'ly toward the center of the `top of the gate, at which point they are united "andconnected'to the top 'ofthe gate'. Adjustably mounted upon these levers 18' are the collars 19'to which the rods 2O are' connected. By this arrangement it will be seen that when either ot' the rods. 20"is pulled' upwardly the free end of the gate will be tilted upwardly' to the' position shown by rdotted lines at the central portion of Figure 1, and ,the other end of the gate will 'slide longitudinally upon the guide rodsV Mby reasonof the cross piece 13 mounted thereon and' ixed to that end of the gate, and 4a' further inovementof said levers 18 will cause the .gate to move to its said open position, as shownk by dotted lines at theleft of Figure 1.

` Moun-t'edfa'djustably upon the upper end' ofeachof the uprights 11 is a br'acliet 21 secured by' set' screws 22 so that it' is both horizontally and vertically adjustable. Pivote'd to the outer end of thev bracket '21 is a sol lever 23 pivoted by'means of the bolt 24, as shown in Figure 5. This lever is preferably made of several pipes telescopically con nected so that it is adjustable as to length.

The outer end of the lever 23 is connected to the rod 2O on the side opposite from the bracket 21 to which the lever is attached, as clearly shown in Figure 3. "Upon the' central portion of the lever 23.1v provide a.

weight 25 adjustably supported by the U- bolts 26. On the outerendot each of 'the levers 23 is a pulley 27, shownl in Figure 1,

and in the top of the bracket 21 isa `guide .device is clearly shown in Figures 3 and 4 and has at its lower end a latch shoulder 33 and is provided-with slots 34 through which the bolts 35 are passed,.and these bolts are -xed to the adjacent upright-s 11. I preferably provide springs 3 6 on these bolts 35 to yieldingly hold the latch body substantially parallel `with the uprights, which springs serve as cushions against the rebound of the gate when forcibly and rapidly moved to closed position, but the springs do not applyenough tension to prevent the latch from moving down by gravity.

In the practical operation of my improved gate operating device and assuming that it is in-its closed position, vit is obvious that.

the gate willbe firmly held against all the strains to which gates are ordinarily subjected. Lateral movement of the gate by pressure from either side is resisted by the cross piece 13 onthe guide rods 16. Longitudinal movement of the gate is prevented by the latch vengaging the cross piece 13 andv vertical movement of the4 outer end of the gate is prevented by the latch device and the cross piece 13 on the )inner end of the gate.

23 may be placed in any conveniently accessible position. Further, the length of said levers may be adjusted by telescoping the sections of which theV lever is formed. Assuming that the gate is closed and it is desired tol open it, then the loperator pulls', downwardly upon the adjacent rope 30. The `rst ei'ecty of this rpull l1s to raise thel yBy reason of the vertically movable and khorizontally adjustable bracket 21 the levers osition, as

move the gate toward an vopen p igure 1 at indicated by the dotted lines in gate isv elevated because of the cross piece 13 and the guide rods 16. During this opening movement of the gate the gate can not move laterally because of the cross piece 13 and the guide rods 16, and after thelevers v19 havel swung past a vertical position'then the gatevwillmove the rest oit the way by gravity to a fully open position.

rlhe adjustable weight25 is arranged so lthe center thereof. Only one end ot the that it substantially counterbalances "the weight of the gate so that the pull upon the rope by the operator need be only very slight in orderk to accomplish the opening or closing movement. The same process-isk used when moving the gate from the open to closed position except that in this case it is not necessary to release the latch.v

I claim asmyinvention:

` l. The combination of a gate, an operat'g ing device comprising two uprights onL opposite sides of the gate, a cross piece fixed to one end of the gate, and having openings in its endson opposite sides of the gate, two substantially horizontal guide rods fixed on opposite sides of the gate and extended through the openings of the said cross piece, a lever pivoted at its lower end Ito said uprights and connected at its upper endto sub stantially the central portion of the top of the gate, and meansifor operating said lever comprising a bracket adjustably mountedat the upper end of each of said uprights, a lever fulcrumed to said bracket, a rod connected to the inner end of said lever and to the aforesaid leverthat is connected kto the gate, and a latch device normally .engaging the said cross piece on the end of the gate, a rope connected `tosaid latch device and slidingly supported on the lever that is attached to said bracket, and means for limiting the movement of the` latch whereby the pull upon ysaid rope will iirst'release the latch and then lower the outer end of the lever, substantially as and for the purposes stated.
